Description
The present invention relates to a nail gun, in particular to a nail discharging and forming structure for the nail gun.
The nail gun is a tool which would be used for buildings and decorations and connects different work pieces together by firing spikes. A conventional nail gun, as disclosed in Taiwan Patent No. 1603818, entitled with “MAGAZINE ASSEMBLY AND A STAPLER INCLUDING THE SAME”, discloses a nail box component and a nail gun comprising the same.
However, for construction materials, such as a spring bed and a light steel frame, in a wire type, a C-type nail gun can be used to complete binding operations of different wires. A conventional C-type nail gun, as disclosed in China Patent No. CN210650540U, entitled with “Nail Clamping Drive Device of Electric C-type Nail Gun”, buckled rings with aligned ends may be formed and may be used for binding the construction materials such as the spring bed and the light steel frame.
However, when withstanding a certain amount of weight, the buckled rings with the aligned ends, formed by the conventional C-type nail gun, are prone to slightly deforming to cause a problem of no closure anymore and are prone to causing the risk that the bound construction materials fall off; and therefore, the conventional C-type nail gun is not suitable for application places requiring weight bearing.
However, in the prior art, if the buckled rings with crossing ends require to be formed, the nail box which continuously discharges nails cannot normally run as the buckled rings may make displacements in a vertical direction when being formed. This is to say, nail inlet can be conducted in a mode of inputting nails one by one only; so that the operation efficiency is low, and the demands in use cannot be met.
A main objective of the present invention is to provide a pneumatic nail gun capable of outputting buckled ring with crossing end and continuously discharging nails.
To achieve the above objective, the present invention provides a pneumatic nail gun configured to form a buckled ring with a crossing end by a plurality of strip nails each, comprising a gun body, a nail box, a formed fork and a nail forming device. The gun body comprises a sliding groove, a nail outlet adjacent to the sliding groove, and a push block with an initial position and an actuation position.
The nail box is fixed on the gun body and configured to place the plurality of strip nails to be sequentially exposed from the nail outlet, wherein a bottom of one of the plurality of strip nails exposed from the nail outlet is at a height same as a top of the sliding groove.
The fork is fixed on the gun body and comprises two forming surfaces with unequal heights, wherein the two forming surfaces are adjacent to one side of the nail outlet opposite to the sliding groove, and a height difference between the two forming surfaces is larger than a thickness of each of the plurality of strip nails.
The nail forming device comprises two jaw arms, two control arms, and a push seat, wherein each of the two jaw arms is provided with a through hole, and two through holes of the two jaw arms are overlapped; one end of each of the two jaw arms forms a jaw, an other end of each of the two jaw arms is pivoted to an end of one of the two control arms through a first pivot, and an other end of one of the two control arms is overlapped with an other end of other one of the two control arms, the other ends of the two control arms are pivoted to the push block through a second pivot; and wherein the push seat comprises a rotating shaft and is slidably arranged on the sliding groove, and the rotating shaft penetrates through the two through holes overlapped.
When the push block is changed to the actuation position from the initial position, the two control arms are driven to drive the two jaw arms to rotate and close the two forming jaws, and to drive the push seat to slide on the sliding groove at the same time, and the push seat pushes one of the plurality of strip nails exposed from the nail outlet to the fork, and an end of the strip nail is staggered by closing actions of the two forming jaws together with the two forming surfaces with unequal heights, and the buckled ring with crossing end is formed.
Accordingly, in the present invention, when the plurality of strip nails are formed into the buckled rings with the crossing ends, respectively, the plurality of strip nails exposed from the nail outlet are pushed by the push seat to the fork; and therefore, the displacements of the buckled rings in the vertical direction when the buckled ring is formed cannot affect normal operation of the nail box. Also, the ends of the plurality of strip nails are staggered through the closing actions of the two forming jaws and the two forming surfaces with unequal heights, and thus the buckled ring with the crossing end is formed, and the use demand on continuous nail outlet is met.
